X-BAY-FILM HOLDER.

- Application led Harch'29, 1921.

To all whom t may concern:

Be it known that I, AAnoN SEGALL, a citizen of the United States, andresident of New York, in the county and State of New York, have inventedcertain new and useful Improvements in X-Ray-Film Holders, of which thefollowing is a specification.

This invention relates to X-ray film holders of the type which isemployed for carry-- ing the film in position for visual inspection as atransparency and for retainingthe film for filing and safe storage underconditions of identification.

Holders of the class herein particularly referred to are related to theuse and carriage of small Xray films, such as are generally used indental or analogous practices as a record of teeth or jaw conditions,and it is the object of my invention to provide in general an improvedX-ray film holder which will possess advantages in point of simplicity,convenience, inexpensiveness, economy in manufacture and use,effectiveness, and general efiiciency, and in which the conditions ofvisibility of the film will be enhanced and the sight will be throughonly the transparency of the carried film itself.

Figure l is a face view of the holder constituting my improvements.

Fig. 2 is a corresponding view with the X-ray film in carried position.

F ig. 3 is a detail cross-section, on an enlarged scale, on the line 33, Fig. 2.

F ig. a is a detail cross-section, on an enlarged scale.v on the line lt-4;, Fig. l.

lFig. 5 is a face view illustrating a moditied construction of theretaining lips.

Corresponding parts in all the figures are denoted by the same referencecharacters.

Referring to the drawings, l designates a card or body sheet, whichconstitutes the entire body of the holder and is provided in suitablelocation, centrally or otherwise,

` with a through opening or cut-away portion,

2, corresponding in area to the size of the X-ray lm which is to becarried and viewed. The body sheet and its opening are preferably ofrectangular contour, and upon its face is carried the desireddesignating description or indication, as at 5, to identify the filmwhich is attached to and carried by the holder for visual inspection andfor filing or safe storage under desired conditions. Said body sheet maybe formed of any suitable material adording the desired thickness SerialNo. 456,744.

' or sti'ness and the slight Hexibility required in the retaining lipshereinafter described,

such as thick vpaper or Celluloid, the latter or a material analogousthereto being preterred, and may be of any adapted color,

though it is preferably opaque, or provided l with an opaque surfacesurrounding its sight-opening 2, and non-transparent.

Adjacent the edges, 6, of the sight-opening 2are provided a set ofperforations, as at 7,

arranged in pairs at diametrically-opposite f sides and at right angleswith relation to the rectangular contour of the opening 2, whichperforations open through slits, as at 8, to the edge of thesight-opening, thus forming a lip, 9, of said edge-portion between there' spective pairs of perforations and .slits at opposite sides. 'llheperforations 7 are preferably of circular contour, with the edges of theslits 8 intersecting at their outer ends a segment of the perforation insuch location as to form a relatively-narrow neck, as

at lO, entering the circular perforation, and wlth the) slits expandingoutwardly from said `neck towards the edge of the sight-opening to forma fan-shaped entrance to the perforation.

lt will be noted that the retaining lips are located within the area ofthe body sheet outside the area of the sight-opening, and that the slitswhich form said lips extend from the edge of the sight-opening and arelocated in the portion of the body sheet which surrounds the area ofsaid opening, whereby the film will be sustained upon the base formed bythe portion of the body sheet which surrounds the sight-opening and beretained by the lips overlying the sustained edge of the film beyond theedge of the opening` as shown in Fig, 2.

To provide an entrance-guide to the slits terminals forming theretaining lips, is

adapted to be formed in a simple operation with a cutting-die in onemovement, and the slightly-curved entrance edges 11 and corners 12 canbe also formed in the same die movement under suitable conditions lwhenthe die cuts down.

In Fig. 5, I have shown one type ofmodified construction lof theretaining lips 9, 1n

which the slits 8 have their opposite edges parallel, thus forming astraight entranceslit of uniform width, and also, in this view, I haveillustrated the lips with a straight non-curved free edge, 14, and theslit corners intersecting the edge 6 of the sight'- opening alsonon-curved, though one or both of said curved features may be employedfor an entrance guide-construction according to desired conditions ofuse. If the lips having the non-curved free edge 14 are emloyed, thelips are preferably shorter and llave their free edge terminating beyondand -@at lthe outer side of the plane of the edges 6 of thesight-opening 2,.as shown.

`Fromthe foregoing description, it will be understood that the improvedholder con- 'stituting my invention provides as an inte lity a 'sin lebody sheet 4having a thgiigh unobsructedl sight-opening the edges ofwhich are so formed that they produce retaining li s for engaging andcarrying the X-ray lm in exposed and unobstructed position at thesight-opening, it`

being sim 1y necessary to insert the film with its e ges in engagementwith the edgelips of the sight-opening, in which position it will besecurely carried for visual inspection as a transparency and for filingunder identified conditions. Thus, in operative use, the relationship ofthe entity body sheet of the holder and the attached film is such thatwhen the film is viewed as a transparendyA by transmitted light nosubstance or material or celluloid sheet intervenes in the line ofvision through the film, and the sight is through only the thicknessofthe transparent film itself. 'Aside from the economic advantages andconvenience and the enhanced results afforded by the iml transmittedlight, there is employed a table placed. My invention is especiallyadapted to these conditions `of use, as it precludes anything in theline of vision through the film other than the film itself and the glasstable-slab, whereas with the film holders as usually heretofore employedthere will intervene in the line -of vision not only the film itself butalso the celluloid backing of the holder as well as the lass table-slab,thus impairing the vision y three superposed thicknesses. v

Having thus described m invention, I claim and desire to secure by ttersPatenti 1. An X-ray lm holder, comprising a body sheet havin anunobstructed through sight-opening an provided with lips loated withinthe area of said body sheet outside the area of the sight-opening and atpoints related to the .top and bottom and side edges of said openinglsaid lips being formed by slits extending from the edge of thesight-opening, and locatedin the portion of the body sheet whichsurrounds the area of said. opening,I whereby the film is sustained uponthe base formed by the portion of the body sheet which surrounds thesight-opening and is retained bythe lips overlying the sustained edge ofthe film beyond the edge o'f the opening.

2. An Xf-ray film holder, consisting of a body sheet constituting theentire body of the holder and having an unobstructed throughsight-opening and provided adjacent the edge of said opening withcircular perforations and-approximately fan-shaped slits extendingtherefrom to said edge and producing intervening lips which are locatedentirely within the edge portion of.

the sheet at the opening, whereby the lips will engage above and uponthe edges of the film with the latter supportedupon the surrounding edgeportion of the opening and thus retain the same in inserted posiltionfor visual and unobstructed inspection as a transparency through thesight-opening.

In testimony whereof I have signed the foregoing specifications.

AARON SEGALL.
